1582 link needed

Somebody should add a link to an article on the Commodore 1582, a dual disk drive that was never in mass production. Only prototypes exist. As a consequence of which, it is in high demand as a collector's item. 216.99.201.57 (talk) 20:37, 4 May 2009 (UTC)[reply]

Yes. And speaking of dual disk drives, there is a 1542, also. It too is in high demand by collectors. Dexter Nextnumber (talk) 07:32, 11 December 2009 (UTC)[reply]

Block size

Block size should be 254, since the first two bytes are reserved by the DOS. —Preceding unsigned comment added by 89.132.118.112 (talk) 15:04, 24 May 2009 (UTC)[reply]

Not really; if you used block-read and block-write commands, and wrote data directly to the disk, you could use the whole 256 bytes. Sequential files and program files, however, DID reserve the first two bytes of each block. They were used to hold the track and sector numbers for the next block in the file. 24.119.237.218 (talk) 18:27, 9 November 2014 (UTC)[reply]
